Police in Nairobi arrested a woman on Thursday who is believed to be the most wanted terror suspect, Samantha Lewthwaite.

A senior Anti Terror Police office said that they arrested the woman after city dwellers blocked a car the woman and two men were using along Moi Avenue, after suspecting that she was the ‘white widow’

Residents held the suspects hostage for a while as they waited for the police to arrive following an earlier warning that Al Shabaab militants were planning possible retaliatory attacks in Kenya.

The three were taken to Railways Police Station where they were interrogated for hours before being handed over to ATPU for further questioning.
